Title: Receiver with multiple antennas
Inventor: WIEDEMANN KURT
IPC: H04H20/00
Filed: 1992-07-08
Granted: 2000-04-15
Abstract: The invention relates to a multiantenna VHF receiver, the RF signal received by each antenna being mixed in a mixing stage assigned to the respective antenna with a signal of a first oscillator, generated in the receiver, and the mixed signals thus obtained, with controllable phase position, being added to form an aggregate signal. The alternative frequencies supplied by an RDS demodulator are stored. One of the mixing stages is used briefly at predetermined points in time for updating the stored frequencies with the associated values for the level of reception quality. If they fall below a predetermined level of reception quality, the receiver switches over to a stored alternative frequency which is accepted as suitable for reception. <IMAGE>

The system comprises an electronic pen (1), functionally integrated with a personal computer (2) for the acquisition and processing the signals associated to the signatures, which can be network connected togheter with other personal computers (2), each one having connected as peripherals an electronic pen (1) that comprises two groups of inertial accelerometers MEMS (A), (B), to capture the kinetic data and also data about contact microvibrations with the writing support, one optical self-referential navigation sensor (ONS), to capture the series of data pairs (dx, dy), as momentary movements necessary in the reconstruction of pen's trajectory and which, together with kinetic data (ax,ay, bx, by) captured by the set of inertial sensors MEMS (A) and (B), represents personal computer (2) input data for sensorial fusion processing and also for creating the conditions to extract the information from the sensorial and psychomotric representation of the user's perspective. The method for assessing the authenticity of dynamic handwritten signature consists, on the one hand, of a first stage of calligraphic reconstruction and visualization of writing thickness and, on the other hand, of applying various conversions and comparisons of ax, ay, bx, by, dx, dy signals associated to the signatures in order to assess their authenticity.
Patent RO-127344-B1 (RO)
Title: Method and equipment for determining edible oil freshness
Inventor: GUTT SONIA
IPC: G01N33/03
Filed: 2010-09-27
Abstract: The invention relates to a method and an equipment for determining the freshness of edible oil. According to the invention, the method is based on the optoelectronic measurement of the surface area of an oil drop (p) located on a thermostated water bath (b), followed by the automatic conversion of said surface into oxidation degrees measured on a scale from 1 to 100 by means of some electronically memorized calibration curves. The equipment, as claimed by the invention, comprises a Peltier element (1) which is D.C. supplied from a 12 V electric power source (2), a hollow laboratory glass (3) fixed with a thermally conductive adhesive (4) to the Peltier element (1), a temperature sensor (5), an electronic thermostat (6), a stereo microscope (7) provided with a lighting system (8) and a video camera (9), an electronic computer (10) and a specialized program (11).
